摘要
由菲醌一步合成９－羟基－９－芴羧酸（ＨＦＣ）。测定了它在乙醇和在１，４－二烷／水中的质子常数。采用摩尔比法测定了溶液中它与Ｌｎ（Ⅲ）所形成配合物的组成，用ｐＨ法测定了配合物的生成常数。合成了固体配合物［Ｅｕ（ＦＣ）２（Ｈ２Ｏ）３］Ｃｌ，并对其性质作了研究。
Hydroxyl-9-fluorene carboxylic acid(HFC) is synthesized from phenanthrene dione.Its proton constants are measured in ethanol and in 1,4-dioxane/water(V:V=1:1).The composition and formation constants of HFC complex with Ln (Ⅲ) in solution are measured by molar ratio method and PH method respectively.The solid complex.(Eu(FC)2(H 2O)3) Cl,is synthesized and characterized.
